1.04 SYSTEM DESCRIPTION A. The system operates as an integrated multiplexed protected premises fire alarm/emergency communication monitoring and control system.
1. Changes in the status of monitored points are indicated at the microprocessor based fire command station (FCS) utilizing distributed processing, peer-to-peer networked, interconnected control unit’s (ICU’s) located throughout the building.
1. SHOW LOCATION OF FCS AND ICU’S.
2. SHOW PRINTER (120 V AC FAN FOLD STYLE) ADJACENT TO FCS.
3. SHOW CRT (WITH KEYBOARD) ADJACENT TO FCS. 4. SHOW EMERGENCY LIGHTING AT FCS.
5. REFER TO NFPA 72 3-220.127.116.11.3 AND 3-18.104.22.168.5.5 FOR REQUIREMENTS FOR LOCATING FCS AND ASSOCIATED EQUIPMENT.
6. SHOW A SMOKE DETECTING DEVICE IN EACH AREA WHERE FIRE ALARM CONTROL PANELS ARE INSTALLED AND THE AREA IS NOT CONTINUOUSLY OCCUPIED (NFPA 72 1-5.6).
a. The network micro-processors continually monitor the communications and data processing cycles of the system.
1) A communications failure indication (print-out, display and audible alarm) occurs at the FCS upon failure of the network communication and data processing cycle.
b. Upon FCS failure, an audible and visual alarm alerts attendant.
1) Complete failure of the FCS does not interfere with the ability of each ICU to perform its functions.
2. Smoke detectors and smoke sensors operate in conjunction with the systems’ alarm verification program.
IN AREAS WHERE ALARM VERIFICATION FEATURE IS DESIRED FOR ADDITIONAL PROTECTION AGAINST FALSE ALARMS OR UNWARRANTED DISCHARGE OF FIRE SUPPRESSION SYSTEMS, ALARM VERIFICATION ZONES FOR SMOKE DETECTORS, OR INDIVIDUAL SMOKE SENSORS OPERATING IN VERIFICATION MODE MUST BE INDICATED ON THE DRAWINGS. REFER TO NFPA 72 3-22.214.171.124.1.
a. The alarm verification operation is selectable by zone for smoke detectors and by individual devices for smoke sensors.
b. The activation of any smoke detector within its zone initiates the alarm verification program.
1) The panel resets the activated detector and waits for a second alarm activation. If within one minute a second alarm is reported from any detector within the zone, the system alarms. If no second alarm within one minute, the system resumes normal operation.
c. The system can display the number of times (tally) a smoke detector zone or smoke sensor has gone into a verification mode. A trouble condition occurs when the tally reaches a pre-programmed number.
3. Smoke sensors act as intelligent and addressable devices. The smoke sensor converts the condition of it’s smoke sensing chamber to an analog value. This analog value is digitized and transmitted to the ICUs and FCS.
a. Actual smoke density and temperature measurements are referenced from average sample measurements and are compared to programmable values of threshold sensitivity.
b. Sensor “dirty” and “excessively dirty” trouble conditions are reported automatically through a maintenance advisory and alert program procedure.
c. The system continuously performs an automatic self-test routine on each sensor which checks sensor electronics to ensure the accuracy of the values being transmitted to the ICUs. Sensors that fail are identified and indicate a trouble condition.
d. System automatically performs NFPA 72 sensor sensitivity testing by:
2) Trouble signal when sensor is outside its acceptable sensitivity range.
4. System individually identifies each addressable initiating device and other addressable monitor functions using multiplexing techniques.
5. System is capable of individually operating each alarm notification appliance, and other control functions, using multiplexing techniques.
6. Alarms are processed by the system at 3 levels of priority:
a. Fire alarms, supervisory and trouble signals take precedence in that respective order of priority, over all other signals.
b. Other alarms that require interaction by the attendant have the second level of priority.
c. Monitored points which do not require interaction by the attendant are the third level of priority.
7. Alarms, supervisory signals, and trouble signals are distinctively and descriptively annunciated.
a. Fire alarm signals are distinctive in sound from other signals, and this sound is not used for any other purpose.
b. Supervisory signals are distinctive in sound from other signals.
1) System differentiates between supervisory device activation and trouble (wiring faults) on independent supervisory service initiating circuits.
c. Trouble signals are indicated by distinctive audible signals. Exception: The same sound may be used for both supervisory signal and trouble signal if distinction is made between signals by visible annunciation.
8. Switches for silencing audible trouble and supervisory signals transfers the audible signal to an identified lamp or other visible indicator adjacent to the switches. The visible indication persists until the condition has been corrected. The audible signal sounds when the switch is in its silence position and no trouble or supervisory condition exists.
a. Trouble silencing switch does not prevent sounding of supervisory signal. Subsequent supervisory signals from other zones causes the supervisory signal to resound. A switch left in the silence position where there is no supervisory off-normal signal operates a visible signal silence indicator and causes the trouble signal to sound until the switch is returned to normal.
b. A silenced audible trouble signal resounds at programmable time intervals (every 24 hours or less) as a reminder that the trouble condition has not been corrected. Re-sounded signal is retransmitted to all locations required of the original trouble signal.
9. All system visual and audible trouble signals and supervisory signals and visible indication of their restoration is indicated at the FCS.
a. Each ICUs visual and audible trouble signals and supervisory signals and visible indication of their restoration is indicated at the ICU.
b. Monitoring of ground fault conditions indicate a ground fault trouble condition at the FCS.
10. Access to the system functions are controlled thru at least 3 levels of access security to prevent program modifications or use by unauthorized personnel:
a. At the lowest level of access the system automatically receives, displays and prints alarms, and performs control-by-event life safety functions. The attendant has minimum access to the system functions:
1) Alarm acknowledge.
2) Print alarm summary.
3) Silence alarms.
4) Perform other basic system functions that require interaction by the attendant (cannot change program parameters).
b. At mid-level of access, the attendant may change user programmable parameters and print all summaries.
c. At the highest level of access, programs may be modified by the system manager (life safety control-by-event programs may be field or factory modified).
d. System access functions (log on, log off, access level authority) are displayed and printed with date, time, and persons name.
11. Additional information may be added to the basic messages required to be printed and displayed for each monitor and control point. Using appropriate programming procedures, the system manager may add up to 5 lines (70 characters/line) of specific instructions and pertinent information to each monitor and control point.
12. Summary reports are displayed and printed at the FCS upon appropriate keyboard or function command. Active control points are identified by an assigned message. Spare control points are identified by a point number. The summary reports can be interrupted and terminated and the system returned to normal operation by a manual reset control or automatically if the system senses a change of status signal. The summary reports include:
a. Current Alarm, Trouble, and Supervisory Conditions: Lists all points not in normal state (print and display).
